Rewrite SSL_add_file_cert_subjects_to_stack

SSL_load_client_CA_file can just call
SSL_add_file_cert_subjects_to_stack.

SSL_add_file_cert_subjects_to_stack itself is rewritten to use scopers
and also give subquadratic running time. Sorting after every insertion
does not actually help. (It would have been faster to do a linear
search.) Instead, gather the names first, then sort and deduplicate.

Finally, add a SSL_add_bio_cert_subjects_to_stack. This is both to
simplify testing and because Envoy code copied from
SSL_add_file_cert_subjects_to_stack, complete with the quadratic
behavior. It is the only external project that depends on the
STACK_OF(T) comparison function. To simplify making that const-correct,
just export the function they needed anyway.

BoringSSL

BoringSSL is a fork of OpenSSL that is designed to meet Google's needs.

Although BoringSSL is an open source project, it is not intended for general use, as OpenSSL is. We don't recommend that third parties depend upon it. Doing so is likely to be frustrating because there are no guarantees of API or ABI stability.

Programs ship their own copies of BoringSSL when they use it and we update everything as needed when deciding to make API changes. This allows us to mostly avoid compromises in the name of compatibility. It works for us, but it may not work for you.

BoringSSL arose because Google used OpenSSL for many years in various ways and, over time, built up a large number of patches that were maintained while tracking upstream OpenSSL. As Google's product portfolio became more complex, more copies of OpenSSL sprung up and the effort involved in maintaining all these patches in multiple places was growing steadily.

Currently BoringSSL is the SSL library in Chrome/Chromium, Android (but it's not part of the NDK) and a number of other apps/programs.
